VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 247,121, datedSeptember 18, 1881.

Application led June 13, 1881. (Model.)

To all whom it may concern Be it known that I, ROBERT SEEGER, of St.Paul, in the county of Ramsey and State of Minnesota, have invented anew and useful Improvement in Vapor-Burners, of which the following is aspecification.

Figure l is a sectional side elevation of my improvement, taken throughthe line y y, Fig. 2. Fig. 2 is a plan view of the same, partly insection, through the line .fr x, Fig. l.

Similar letters of reference indicate correspending parts.

The object of this invention is to promote convenience, safety, andefciencyin the use of vapor-burners.

The invention consists in a vaporburner constructed with an inlet orretort tube, the burner-tube having jet-hole, auxiliary jet-hole,air-inlet hole, and interior chamber, the tiptube having holes openinginto the upper part of the interior chamber, the disk to lock`the tubein place, and the shields to protect the auxiliary jet and confine theheat around the inlet or retort tube, as will be hereinafter fullydescribed.

In the accompanying drawings, A represents the inlet or retort tube, theupper part of which projects outward and is countersunk, and has ascrew-thread formed in its inner surface to receive the end ot' the tubeB, leading to the liquid-reservoir. The cavity of the tube A, at itslower end, communicates with the jet-hole C in the lower part of theburner D. The amount of vapor passing through the jethole C is limitedby a thumb-screw, E, the forward end of which is tapered to correspondwith the taper of the said jet-hole C. The interior of the burner D isturned out from near its upper end to a point a little above the jetholeC, forming a chamber, F, in the interior of the said burner D.

G is a tube, the upper endof which is slitted or perforated to form aburner-tip. The tube G fits into the interior of the burner D, and uponthe outer surface of the part of the said tube G that enters the upperend of the burner D is formed a screw-thread, to it into a screwthreadformed in the inner surface of the upper end of the said burner D. Thetube G is made of such a length that its lower end may extend below theshoulder at the bottom of the chamber F. In the tube G, at the upperpart of the chamber F, are formed holes L, leading into the saidchamber.

In the lower part of the burner D, next the lower part of the inlet orretort tube A, is formed a hole, H, for the auxiliary jet, so that thellame of the said jet will impinge against the lower part of theinlet-tube A to heat the said tube and vaporize the liquid passingthrough it.

In the lower part of the burner D, directly opposite the inlet-tube Aand just above the jet-hole C, is formed a hole, I, to admit air to mixwith the vapor and prepare it for combustion. `"With this construction,by screwing the tip-tube G up or down the air-inlet hole I can becovered less or more, to regulate the supply of air, as desired.

Upon the sides of the inlet-tube A are formed wings J, which overlap thesides ofthe burner D and serve as shields to protect the auxiliary jetand confine the heat around the said inlettube A.

Upon the screw-thread at the upper part of the tip-tube G is screwed adisk, K, which, when the said tip-tube G has been adjusted, can bescrewed down against the upper end of the burner D, to serve as ajam-nut for locking the said tip-tube in place. The disk K is made ofsuch a size as to cover the space between the burner D and inlet-tube A,so as to prevent the heat and llame of the auxiliary jet frominterfering with the llame from the burner-tip.

The inlet-tube A, burner D, and shields J are cast in one piece, so asto bring the lower end of the inlet-tube A as close as possible to thejet-hole C, so that the vapor will have the least possible distance totravel before reaching the burner.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patentl. A vapor burner constructed substantially asherein shown and described, consisting of the inlet or retort tube A,the burner D, having jet-hole C, auxiliary jet-hole H, airinlet hole I,and interior Chamber, F, the tiptube G, havin g holes L, opening intothe upper part of the chamber F, the disk K, and the shields J, asforth.

2. In a vapor-burner, the combination, with the burner D, havinginterior chamber, F, airinlet hole I, and auxiliary jet-hole H, of thevertically-adjustable tip-tube G, having holes Io L, substantially asherein shown and described, whereby a returncurrent of gas to thejethole is formed and the entrance of air is regulated, as set forth.
